T 0 all whom, it may concern:

Be it known that we, IVALTER HAMER and JOHN HENRY I-IowARTH, subjects of the King of Great Britain, and residents, respectively, of The Willows, Sharples Park, Astley Bridge, Bolton, in the county of Lancaster, England, and 96 Ashworth Lane, Bolt-on, in the county of Lancaster, England, have invented a certain new and useful Improvement in Spinning-Mules for Use in the Production of Yarns or Threads of Fibrous Substances, of which the following description is a specification.

In the production of yarns or threads by spinning mules, as the carriage runs in or moves toward the delivery rollers to permit the yarns or threads to be Wound upon the spindles, as well as during the period of backing-off, the fallers which guide the threads to form the cop of the desired shape move during the said running in of the carriage through such vertical paths and in such a manner as is found necessary to carry out the eflicient guiding of the thread to attain the object referred to. During such motions of the faller which guides the thread, the counter faller Wire is brought into contact with said threads to keep them in a state oftension without straining the yarn, so that firm and solid cops are produced and snarls are avoided. However, we have found that under ordinary conditions the weighted levers which press the faller wire into contact with the series of threads, are required to move so suddenly and to change their direction of motion so often that by the inertia on the one hand and momentum on the other hand of said weighted levers the evenness of the tension of the yarn is not attained with that regularity which is desired; and especially is that the case at certain parts or during certain port-ions of the backing-off and winding operations when the jerky actions of said faller wires have the effect of causing breakages of the threads greatly to the inconvenience of the attendant. Further by the irregularity between the excessive tension when a change of direction of motion takes place (which brings into action the inertia of said weighted levers) and the action in the opposite direction when the motion of said levers is being arrested the tens1on on the threads is greatly interfered with. To obviate these disadvantages many devices have already been proposed to be used, but in most cases means have been employed which actuate the weighted levers so that their weight on the counter faller should be thereby varied. However, according to our pres ent invention we do not make use of additlonal moving parts to attain our object but make use of such devices as will have a neutralizing effect on the irregularities caused by the inertia and momentum hereinafter referred to.

In the accompanying sheets of drawings which are illustrative of our invention: Figure 1 is a sectional end elevation of sufficient of a mules carriage to show the appli cation thereto of our improved parts. The part of the carriage where the section is taken is to show the connections from the faller shaft to the lever which actuates same. Fig. 2 is a similar view to Fig. 1 but the section is taken at another part of the carriage to show other devices hereinafter described. F ig, 3 is a front elevation of sufficient ofsaid mules carriage to illustrate the parts shown by Figs. 1 and 2. Fig. 4: is a sectional view of a part in detail hereinafter described. Figs. 5, 6 and 7 are drawings illustrative of several types of springs which we may employ to carry out our invention. Fig. 8 is a drawing in detail illustrating a further modification of our invention.

In carrying our invention into effect we make use of the usual flexible connections a between the quadrants or levers b on the counter faller shaft 0 and the weighted levers (Z which actuate same, or which cause said counter faller shaft 0 to be moved to put the necessary tension on the yarn, but intervening between said weighted levers d and the levers Z) we mount yielding springs f which will now form part of the flexible connections a hereinbefore referred to. The mounting of these springs f in the positions shown enables them (when a sudden change of direction of motion of the counter faller g puts a strain upon said springs f to overcome the inertia of-the weighted levers d and other parts) to yield and prevent any jerky act-ions, while yet maintaining approximately the same controlling influence over the counter faller 9 that the weights on the weighted levers (Z when in their stationary positions exercise thereon. On the other hand, when, by the falling of the weighted levers (Z such weighted levers attain certain momentum which has to be arrested by the pull of the faller wire upon the threads, said springs f also yield to bring about the desired evening or regulating influence in the opposite direction to that in respect of inertia above described, thus the actions of the faller wire 9 upon the series of threads is approximately even throughout the whole of the backing-otl and winding operations irrespective of any sudden or irregular motion required to be carried out by said weighted levers to meet the necessities of the main faller during the time stated. As it is necessary to actuate said counter faller g to relieve it from pressing upon the threads when the carriage reaches a certain part of its path of motion, in order to secure the same resilient connections between the counter faller shaft 0 and the lever it which actuates same through means well understood, we so construct the connecting rod it which couples the lever m on the counterfaller shaft 0 to the lever h operating said rod 70, that this rod is now formed in two parts it, 7J1, with a spring p intervening between one part and the other to afford the necessary resilience for a certain space but to be rigid when forced vertically by the in cline g fixed upon the lever it coming in contact with the stationary or fixed bracket r as the carriage is running in toward the delivery rollers.

Mounted upon the upper and lower rods 70, is the spiral spring 3) which has one extremity secured to the upper rod 7: and the other to the lower rod 76 (the tension of said spring in its normal position keeping the ends of said rods against each other) in order that as said rods are acted upon by the strain on-the yarns or threads when same are arresting the motion of the levers (Z and 7b as hereinb-efore explained said spring 7) will yield and permit said action to be transmitted in a resilient manner, while when said rods are moved upwardly, the upper end of the lower rod being in contact with the lower end of the upper rod 70 will positively force said rod in said up ward direction, thus the actions are of a negative character in one direction and a positive or rigid character in the other direction, the latter being necessary in order to positively carry the faller into its proper position for purposes well understood, while the former will bring it with that yielding resilience in the other direction when acted upon by the threads or yarns thus attaining the object we desire. As will be observed the tube or sleeve 72 may be fixed upon the rod is, the rod 70 sliding within said tube, while the spring 39 surrounds said sleeve and is fixed to the rods 7c, 70 by which means the sleeve or tube 19 will keep said rods 7:, 76 in perfect alinement.

lVhenever conditions arise whereby the rebounding of the springs f and p happen to synchronize with the movements of the several weighted parts, so as to interfere with the evenness of the actions of the faller wires upon the threads, we make use of resilient devices preferably produced by the actions of air within a cylinder to carrying a piston 11, such cylinder a being fixed upon the part a while a piston 7) working within it is fixed upon the part a having the spring f surrounding it, thus the actions of said piston upon the air contained by the cylinder are such as to form resilient bufi'er devices which ill practically prevent rebounding and yet permit the several parts to yield as hereinbefore described.

It is obvious that the springs f when not mounted within boxes or sleeves may beof any form or shape as for example the for1nsillustrated by Figs. 5, 6 and 7, thus in Fig. 5 an ordinary helical springs f is employed, in Fig. 6 a C shaped spring f is made use of while in Fig. 7 two bent springs f are illustrated.

In Fig. 8 the rod is is arranged to be of the ordinary form, the resilience desired to be allowed to the lever at being obtained by forming said lever in two parts m, m one being hinged to the other. The rod is is connected to the part m and a spring 29 extends between the projection m on the part m and the extension m on the part m. The upward movement of the rod 70 is transmitted positively to the shaft 0 by the pro jection m on the part m taking against the projection m formed on the part m, while the spring p allows the desired resilience in the opposite direction.

Such being the nature and object of our invention, what we claim is 1. In a spinning mule a counterfaller shaft, an actuating lever, a connection between the actuating lever and the counterfaller shaft, said connection being capable of positive action in one direction and yield ing action in the other direction, a weighted lever, a flexible connection between the counterfaller shaft and the weighted lever, and a yielding member interposed in the flexible connection.
